is there any further interest in trying to figure out what happened
there? as someone else explained, the libmudflap and libmudflap-devel
packages are built from the gcc source rpm, so i'm curious as to how,
in the .spec file, one ties those generated packages back to the
original gcc source, to make sure they all get updated equivalently
(if that is, in fact, what is supposed to happen).
i downloaded the most recent gcc source rpm and this appears to be
the relevant snippet from the .spec file:
=====
%package -n libmudflap
Summary: GCC mudflap shared support library
Group: System Environment/Libraries
%description -n libmudflap
This package contains GCC shared support library which is needed
for mudflap support.
%package -n libmudflap-devel
Summary: GCC mudflap support
Group: Development/Libraries
Requires: libmudflap = %{version}-%{release}
Requires: gcc = %{version}-%{release}
%description -n libmudflap-devel
This package contains headers and static libraries for building
mudflap-instrumented programs.
=====
i'm no expert at .spec files (especially ones that generate multiple
packages), but is the above supposed to guarantee that, if one updates
any one of gcc, libmudflap or libmudflap-devel, then *all* of them
must be updated identically?
and this is probably a silly question, but is there a reason that
libmudflap doesn't have a "Requires" directive for gcc, whereas
libmudflap does? i probably need to do more reading here.
